6 Claims.

This invention relates to separable fasteners and particularly to the sliders for devices of this class; and the object of the invention is to provide a reversible lock slider having means for retaining the slider against upward movement on vertically arranged stringers to prevent opening of the stringers from the lower end thereof. especially in applying devices of the kind under consideration to leggings and other articles of apparel and other merchandise normally arranged in the position stated; a further object being to provide a locking or retaining means constituting part of the nger piece or pull of the slider and consisting of two lingers or pawls, one adapted to enter the channel of the slider to engage one or more of the links of a fastener stringer and the other cooperating with the slider to retain the pull against accidental displacement from its locked position; and with these and other objects in view, the invention consists in a device of the class and for the purpose specied,

which is simple in construction, eiiicient in use, and which is constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts ofmy improvement are .designated by suitable reference characters in each of the views, and in which:-

Fig. illustrating one use of my invention.

Fig. 2 is a longitudinal sectional view through the lower end portion of the fastener shown in 5 Fig. 1 on an enlarged scale, the section being on the line 2-2 of said ligure.

Fig. 3 is a face view of the structure shown in Fig. 2 with parts in a different position and in section.

Fig. 4 is a partial section on the line 4-4 of Fig. 2; and,

Fig. 5 is a view similar to Fig. 3 showing only a part of the construction and showing a modiiication.

In leggings and other articles of apparel as well as articles of merchandise which open from the lower end of a vertical arrangement of the fastener, it is desirable to retain the slider against upward movement on the stringers, or. in other 50 words, to prevent the stringers from opening, especially where the stringer lower ends are subjected to stress tending to open the same.

To illustrate one use of my invention, I have diagrammatically shown at 5 in Fig. 1 of the 55 drawing a legging or one leg end of .a garment of any kind or class, such for example 'as childrens snow suits, ski suits, running trousers 'and the like. At l, I have indicated a separable fas- -tener having a slider I to open the garment part 60 5 from the lower foot end portion l thereof to 1 is a perspective view diagrammatlcally any desired point upwardly of the leg of the garment as indicated at'll.

'Ihe separable fastener C consists, as is customary. of mounting tapes or side portions il) and Il, preferably provided with beaded edges Illa. lia, to which are secured the coupling links or scoops i2 and i2a which are adapted to be coupled and interlocked by the slider 1 movable lon- Eitudinally thereof. It ls also customary to provide a linger piece or pull Il for the slider, by means of which the same may be operated to open and close the fastener. The slider 1 has the usual narrow or contractedend portion I4 and the wider or ared end portion i5, the latter having channels which are subdivided by a substantially v-shaped web li, the channels converging into one channel l1 at the narrow end ii of the slider.

One side wall, preferably the outer side wall,

adapted to extend through an aperture 2l formed in the wall of the slider 'l so as to enter the channel I1 to engage one or more of the links i2, i2a

of the fastener stringers i0, il, depending entirely upon which sidey of the finger piece or pull the pawl 20 is arranged, it being understood at this time that, if desired, two of the pins or pawls 20 may be provided to engage the links of both stringers.

In spaced relation to the pin or pawl .20, the nger piece or pull I3 is provided with a lock linger or pawl 22, somewhat hook-shaped in form and which is adapted to frictionally pass over the rounded end portion 23 of the web I6 and to enter a recess or depression 2l formed in the outer or lower surface of said web as clearly seen in Fig. 2 of the drawing. When in this position, the linger piece er pull ills positively retained against accidental displacement when in its locked position so as to prevent movement of the linger piece or pull, especiallyl in normal uses of the device, it being understood, however, that the finger piece or pull Il may be forcibly disengaged from its locked position and swung into the dotted line position shown in Figs. 2 and 4 and the full line position indicated in Fig. 3 in the operation of moving the slider longitudinally of the stringers to open and close the same. In the last named position of the pull, the pin or pawl 20 is out of engagement with the channel Il as well as the links of the fastener stringers.

In Fig, 5 of the drawing. I have shown another form ofconstructlon which consists primarily in changing the position of the finger or pawl 22 on the linger piece or puli. In this iigure,I have indicated at I3a aiinger piece or pull similar to that shown inthevothergures, except that I have substituted for' the member 22,'v a similar that provided' with thepinpr pawl 20a, adjacent hook-shaped member 25 arranged at one side edge of the pull i3d, preferably the edge opposed to tion yas to register with or pass between two of 1 the links I2 of the strlnger, whereas',t`he pin 20a isfadap'ted to be arranged between the links I2 of the opposed Stringer at a point in. longitudinally spaced relation to the engagement of the finger 25, with the links I2; With, this construction, in additionfto. securelyretain the pull I3a in its locked or operative position, the'inger or pawl 25 also serves as additional means for securing the slider `against movement on the stringers.

In the accompanying drawing, the slider l as well as the finger piece or pull I3 are represented as die cast or molded parts, but my invention is not limited in this respect nor to the particular arrangement of pawls or' locking elements employed.

It is desirable that the `locking finger or pawl have what might'be termed a. camming or wedgin'g action in-order to be iirmly 'and securely held in operative position. `This"type'o`f slider may be used in any form or use of separable fastener by adapting the'slider and -iinger piece to the distinct uses.

lthe pivoted end thereof, the slider having an aperture through which said pin passes in engaging one of the stringer links to retain the'slider against movement longitudinally of the stringers in one direction, and means on the pull outwardly 4of said pinfforfengaging the wide end portion of the slider to retain the pullin 'locked' position against accidental displacement.

2. In separable .fasteners employing stringers having interengaging coupling links, a slider movablelongitudinally of the .stringgrs to couple and uncouplesaid links, said slider having`a contracted end portion and a wide flared end portion, a

lock element pivoted to the slider inwardly of the4 end portions thereof, said element comprising' a nger piece or pull having a lock-pin adjacent the pivoted end thereof, the slider having an aperture through which `s'aidpin* passes` in engaging one of the *Stringer-links to retain the slider against movement longitudinally of the stringers in one direction, means on the pull outwardly of said pin for engaging the wide end portion `oi! the slider f to retain the pull in locked position against accidental displacement, and said'means comprising a hook-shaped `pawl projecting from one side surface ofthepull. ,Y g 3.
